Abstract
High rate of Population growth, coupled urbanization and industrialization results for high demand for land. In order to increase availability of land, the government of Ethiopia has introduced the construction of multipurpose buildings which allows vertical expansion rather than horizontal. Due to this mode of expansion there is a need to establish a land tenure system which considers the use and registration of multipurpose buildings in 3D environment. In Ethiopia, using aerial photography for cadastral mapping is not a new thing for the processes of extraction of 2D cadastral layer but most of the time it is not seen using for 3D cadastral registration system. Method of feature extraction in 3D environment using aerial photograph is cheaper than that of LIDAR. 2D cadastral and property registration system cannot solve the problem related to building height and was difficult to standardize building construction, even if it has been employed for a long period of time. 2D cadastral registration system is not able to clearly indicate the property right of individuals having multi-purpose buildings. Due to this it is difficult to register, manage, and visualize their institute condition for decision making and for a given applications such as infrastructure development. This study is intended to examine the applicability of Aerial photo and CGA script for automated 3D objects modeling, design cadastral information system for commonly owned residential building and commercial centers, examine legal and institutional aspects of 3D property information and representation system for land registration, management, administration, urban planning and decision making process in Bahir Dar town by applying 3D GIS techniques. The existing 2D cadastral registration system was carefully assessed and the gaps are well identified prior to propose a new registration system. The ESRI 3D city engine module was used to reconstruct the multipurpose buildings after carried out photogrammetric processes. CGA rule was written for each textures such as wall, roof, road, façade, window and door to produce an automated 3D urban model. From the study it is found that the existing cadastral registration system in Bahir Dar land management and development office does not consider the registration of multipurpose buildings. Due to this a new registration system was proposed to incorporate multipurpose buildings in the future cadastral registration processes. It was also found that a 3D model cadaster supports better in managing increased demand of land and building constructions.
